A Proctor woman was hurt when she rear-ended a trailer on Route 4 in Rutland Town, according to Vermont State Police.

Police said Jessica C. Ellis, 27, was driving her 2006 Honda civic west near the Quarter Line Overpass at about 7 a.m. Tuesday, when she hit the back of a 2005 Volvo tractor-trailer driven by James Haggerty, 52, of Londonderry, N.H.

Police said the truck had slowed while climbing an extended hill.

Police said Ellis suffered an injury to her ankle. An 8-year-old riding in the car with her was taken to the hospital as a precaution but was unhurt — a fact police attributed to the child being properly secured in a booster seat with a lap and shoulder belt. Haggerty was also uninjured, according to police.

Ellis’ car sustained damage to the front hood, windshield and front side panels, according to police, while the truck had minor damage to its rear bumper. Police said the low safety bumper on the trailer kept Ellis’ car from going under the larger vehicle, which would have caused further injury.
